Works fine with mem=2500M, but blows up with mem=3G or without any override and full 4G complement in use.

This board (ASUS A8N-SLI) does use NVIDIA nForce4 chipset with
bios-option to map (hoist) "excess memory" out from first 4G to
higher physical addresses so that it can be accessed by the
processor.

This board has no AGP at all in it, but it does have lots
of PCIE, and a bit of PCI-X thrown in for "legacy cards". Somehow that detail breaks things when the machine really
should use bounce-buffering, or something similar -- I don't
know if Nvidia  nForce4 chipset does have IOMMU, though...

If Nvidia did omit such essential piece of hardware from
a modern chipset, I do find it amazingly short-sighted...
(Of course they don't yield documentation of the chips to
public so that I can't quickly verify this detail...)


I'm having the same problem I have the same ASUS motherboard running a dual core Athlon and 4 gigs of ram. Worked fine with the 2.6.13.2 kernel which I am now running but fails with 2.6.14. No DEBUG related issues for me. I do have a PCI VGA card in it.

Sure would like to see these X2 problems fixed. Rather not have to run down to the datacenter all the time. :(

Bootdata ok (command line is ro root=/dev/sda4 vga=1 notsc)
